The New England Patriots officially placed tight end Rob Gronkowski on the physically unable to perform list on Tuesday.

Gronkowski, was placed on PUP along with wide receiver Julian Edelman, offensive lineman Nick McDonald and tight end Jake Ballard.

On top of the four players listed on PUP, the team also listed four more on the Non-Football Injury list. Wide receiver Mark Harrison, defensive lineman Armond Armstead, offensive lineman Matt Stankiewitch and defensive back Kannoris Davis.

Gronkowski being placed on PUP is no surprise. With a series of several operations on his left forearm and disc in his back, the All-Pro tight end is still rehabilitating. The 24-year-old, as well as any other player on PUP, can be taken off the list at any time during training camp or pre-season, but will be sidelined for six weeks once the season begins.

The Non-Injury Football list is basically the same as the Physically Unable to Perform list except for the players are suffering from injuries that happened off the football field.

The best news that can be taken from this release is both rookie receivers, Aaron Dobson and Josh Boyce, were not placed on any list, which means they will be ready for practice when the team begins on Thursday, July 25. Notable veterans Sebastian Vollmer, Devin McCourty, Dan Connolly and Alfonzo Dennard also escaped being listed, which is a very good sign for the team.
